We’ve all wondered, at least once, how it feels like when we die. Is it a sense of relief, pain, or happiness? Or, we really do see a light at the end of the tunnel.

For us, it’s really hard to know, but, thanks to scientists, now we can know. Watching a horror movie will probably cause you chills and fear, especially a killer with an ax chasing it’s victim, and according to the scientists from the American Society of Chemists, that’s exactly what you’ll feel in that situation, and you’d react in the same stupid way the actor did. Those movies explain just how you would react, you could ether run or stand back and fight, or, just scream.

Everything starts with the simple sense of fear, which main’s purpose is to prepare you to react when you are in danger. This affects the part of the brain called the thalamus, which is sensitive to stress. So everything about our fear is about a chemical reaction in the brain we come to a state of “fight or flight” for what we would like to thank the hypothalamus. So, in such stressful situation, our hypothalamus stimulates the adrenal gland to secrete adrenalin, and then it goes to the liver and stimulates the secretion of sugar in the blood. So, then you come in a state you’ve never been, you have kind of superpowers.

If you can’t escape your killer, then your next reaction is screaming. And then, pain. Pain is a signal sent to the brain, that something bad has happened to us, and it should now happen ever again. And, then you’ve got the ax in your neck. What next?

First of all, you’ll be experiencing clinical death, which means your heart stops beating and you stop breathing. So, at this point, your brain is still active, and then, magic happens. In fact, recent studies have shown that the brain decline in hyper condition of perceptual neuro-activity. Which means, it works like crazy, and that is the reason that some people who have survived clinical death described that they had saw the light, or some other things, according to the scientists.

However, if there is no help near you when the clinical death happens, then the brain stops working and then comes the biological death. So, it is clear that if you see the light, and no one helps you in that moment, then the lights go out forever.
